The Malthus RepRap is a cheap, fast-to-replicate, scalable and simplified Prusa Mendel. It will be available in small (100mm x 100mm x ~50mm) and large (200mm x 200mm x 100mm) varieties although the design can be scaled to any dimension via the machine parameters in config.scad.

Features

Parametric Scaling - the build_volume = [x,y,z] variable in configuration.scad allows you to build a Mini-Prusa with the build volume of your choice (within reason)

Less Printed Parts / Smaller Printed Parts - a reduced vitamin and printed part count compared to the Prusa-Mendel. Crucially the frame vertex pieces were redesigned from the ground up to reduce the print time and combine several parts.

Less Screws - Yeah, that's right. We got rid of screws. This might appear slightly insane - but heres why: Metric screws were always a problem to source in North America and no doubt imperial screws would be just as difficult to source in the Metric world. To end this problem once and for all we removed all but 2 screws (extruder mounts) in the Malthus design by replacing them with printed components and zip ties.

Larger build volume / total volume - by redesigning the Malthus vertex pieces and x/y carriages the Malthus manages to fit more print volume in a smaller machine - making Malthus more portable and desktop-friendly.
